How to Crop an Image on Mac Using Preview

Most likely you have already used the Preview app countless times, maybe even without realizing it. It is the default program for viewing images and PDF files on Macs. However, many users miss the cropping tool because it is not initially visible when you first open Preview.

Double-click to open the image you would like to crop. This will automatically launch Preview.
If you have another software set as your default editor, you can also right-click on the image, select Open With and then click Preview.
Click the Show Markup Toolbar icon to reveal your editing tools.
Click the Selection Tool icon to choose what shape your cropped image or PDF will be.
You can choose Rectangle, Elliptical, or Lasso (the Lasso and Smart Lasso options allow you to freehand any shape you want).
Click and drag the mouse over the area of the image you would like to keep. Eight expandable blue dots will appear over your selected area, and everything on the outside of the border will be cropped out.
If needed, you can continue to adjust the selected area to be cropped by clicking and dragging one of the blue dots.
Once you have set your crop border, click the Crop icon. You can also press Command+K on your keyboard to complete the crop.
If you don't like your cropped photo, simply click on Edit and select Undo Crop to start over.

The picture cropping tool is just one of the useful features in Preview. You can also resize, add text, rotate, adjust colors, remove the background, sign a document, or even extract part of an image and paste it on top of another image using Smart Lasso. There's a lot to explore! For basic photo editing, it’s all you may ever need.
